Relationship between rainfall and overland flow in Okayama University of Science where the investigated contributing area were 10 (ha) and the ratio of the area were a green track of land and a grove : 47%, a playground and a parking place : 11% and a schoolhouse and a road : 42% was investigated. 1) In hydrograph, the behavior of rainfall intensity (mm/H) was related to the behavior of overland flow (m^3/H). The peaks of hydrograph were observed with above 0.5 (mm/H) rainfall. 2) The coefficient of correlation between rainfall (mm/H) and overland flow (m^3/H) was 0.44 (p<0.01) and ratio of contribution was 19.4%. 3) The relationship between total rainfall (mm/a time) and total overland flow (m^3/a time) were recognized high correlation (r=0.91,p<0.01) and the equation of the regression line was : Y=56.8X+434 and ratio of contribution was 82.8%.
